Adjustable Wire-Guiding Rollers for Precise Multi-Wire Stone Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-wire frames for cutting stone blocks into slabs face challenges in achieving precise cuts when dealing with blocks of varying lengths, as the distance between wire-guiding rollers is often not ideal, leading to suboptimal wire guidance and reduced precision in cutting smaller blocks.
Innovation Solution
A multi-wire frame with adjustable wire-guiding rollers, driven by motorized mechanisms, allowing for automatic adaptation to the length of the block being cut, ensuring the diamond wires remain straight and aligned, even for blocks of different sizes, by varying the distance between the rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the distance between wire-guiding rollers is fixed for large blocks, then cutting precision for large blocks is improved, but cutting precision for small blocks deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the distance between wire-guiding rollers adjustable rather than fixed. The multi-wire frame allows the wire-guiding rollers to be positioned at different distances from each other depending on the block size being cut. This dynamic adjustment capability enables the system to optimize cutting precision for both large and small blocks, resolving the contradiction between fixed-configuration precision and variable-adaptability.
2Manufacturing precision
If multiple fixed-distance machines are used to handle different block sizes, then cutting precision for all sizes is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies the universality principle by designing a single multi-wire frame machine that can handle multiple block sizes through adjustable wire-guiding rollers. Instead of requiring separate machines for different block size ranges, this universal machine can be configured for various cutting scenarios by adjusting the roller positions, thereby reducing the total number of machines needed while maintaining cutting precision across different sizes.
Solution Approach 2:
The adjustable distance mechanism between wire-guiding rollers provides dynamic reconfiguration capability, allowing one machine to replace multiple fixed-configuration machines. This dynamic adaptability eliminates the need for maintaining a fleet of specialized machines, reducing overall system complexity and operational costs.
3Adaptability or versatility
If the distance between wire-guiding rollers is increased to accommodate small blocks, then adaptability to small blocks is improved, but cutting precision for small blocks deteriorates due to inadequate wire guidance
Solution Approach 1:
The patent resolves this contradiction by enabling dynamic adjustment of the wire-guiding roller positions. When cutting small blocks, the rollers can be positioned closer together to provide adequate wire guidance over the increased distance, thereby maintaining both adaptability to small blocks and cutting precision simultaneously.

AI summary
A multi-wire frame (12) for cutting blocks of stone material comprises two columns (14, 16) each of which is provided with a slide (18, 20) designed to move along the respective column (14, 16). At least one multi-groove drum (22, 24) is provided on each slide (18, 20). The multi-groove drums (22, 24) are designed to engage with a plurality of cutting wires which extend between the two slides (18, 20). The multi-wire frame (12) is provided with two wire-guiding rollers (26, 28) designed to guide the wires along the cutting section. The multi-groove frame is characterized in that it comprises means for adjusting the distance between the wire-guiding rollers (26, 28).
